Why Pictulab for JPG to TIFF?
Completely free
Convert as many JPG files to TIFF as you like — no sign-up, no watermarks, no daily cap.
Instant
Conversion runs on your own machine, so there is no upload, no queue and no server wait.
Private by design
Files never leave your browser. Nothing is uploaded, nothing is stored, nothing is shared.
Batch processing
Drag in dozens of files at once and download them all together when they finish.
Converting does not restore what was lost
This is the most common confusion around this conversion: moving to a lossless format does not undo loss that already happened. A JPG compressed at 70 % converted to TIFF still has exactly the same artefacts, only now they occupy forty times the space.
The benefit is forward-looking: from that TIFF you can edit and save as often as you like without degrading further.
When you will need it
When a printer asks for it for a run, when an archive or library requires a preservation format, or when you enter a professional workflow where JPG is not accepted as source material.
Outside those contexts, converting to TIFF only multiplies the file size for no gain.
Processed locally
The TIFF is written in your browser, without uploading the image to any server.

Frequently asked questions
Does it improve the photo’s quality?
No. TIFF preserves exactly what was in the JPG, compression artefacts included. What you gain is that it will not degrade further on each save.
Then why convert?
Because the destination demands it. Many printers, agencies and document archives accept TIFF only — and because from here you can edit without accumulating loss.
How big is the result?
Width × height × 4 bytes. A 12-megapixel photo runs around 48 MB versus 3–4 MB as JPG. That is inherent to an uncompressed format.
Is it a valid TIFF?
Yes, with a complete header and image file directory. Not a PNG with the extension changed, which is what plenty of browser-based converters hand over.
Does it keep EXIF data?
No. The image is preserved; camera metadata is not carried across.
